To check those counters press the button [Read transmission errors], and to delete (zeroing of counters in the memory of the converter) press [Delete transmission errors]. In case of parity errors or frame errors, should be checked the ADA-4040PC8 converter's configuration and correctness connection of RS485 bus to RTU and JCT converter ports. -
Page 11: Operation
ADA-4040PC8 7. OPERATION ADA-4040PC8 is a bidirectional converter of JCT-ASCII protocol to MODBUS-RTU protocol, with the possibility of converting the baud rate, data format (number of data bits, parity bit, stop bits) and the type of RS485 interface to RS422. -
Page 12: Implementation Of The Modbus-Rtu Protocol
8. IMPLEMENTATION OF THE MODBUS-RTU PROTOCOL ADA-4040PC8 protocol converter allows connecting controllers with the JCT-ASCII protocol as SLAVE to the RS485 bus MODBUS- RTU. The length of RS485 bus can be extended (next segments of 1200 m) by the use of ADA-4040 repeaters or ADA-4044H HUBs RS485. -

8.3.1. 0x03/0x04 FUNCTION - READING OF THE 16-BITS VALUE OF REGISTERS [4X/3X- REFERENCES] Function 0x03 / 0x04 are used for readout the registers from ADA-4040PC8, in which are available measurement values and status values of JCT controller. The measurement values readout form MODBUS-RTU register is presented by a 16-bit register. -
Page 14: 0X06 Function - Save Values To 16-Bits Register [4 X-References]
MODBUS registers are in the format of the 16-bits integral number with the character (in C/C++ type short int). The value saved in the MODBUS register of ADA-4040PC8, is obtained by multiplying real measurement value by the DW factor, according to the following algorithm. -
